Any contactors adopting concrete cutting machine instead of traditional hacking tools ? Why are concrete cutting machine not popular as I try to goggle with no results .

Converting windows to doors will be clean and neat with electric tools 

I remember someone telling me this before that concrete cutting machines uses steel saw to cut the concretes that are very tough but its also an expensive tool because the edges of the steel saw is coated with diamond to enable it to cut through the concrete flawlessly, so its more of an issue with the cost of the tool itself, so only those bigger firms involved in prefab will have such tools
